How often you do you look
weather at night and look
of shining stars, right?
brighter than the others
up to the sky? Wait for
at it then you will see
Some of them are bigger
They are the planets
the clear
thousands
and shine
Let’s take
a look at our solar system, shall we?
The star at the center of solar system is Sun.
Our sun formed approximately 4.6 billion years ago from the
gravitational collapse. It is a G-type main-sequence (G2V)
based on its spectral class and is informally referred to as
a yellow dwarf.The Sun is important source of energy for
life on Earth.
The closest planet to the Sun is Mercury.
The smallest solar system planet without satellites. It
is named after the Roman deity Mercury, the messenger to the
gods. Having almost no atmosphere to retain heat,surface
temperature varies from −173°C at night to 427°C during the
day.
The second planet to the Sun is Venus.
It is named after the Roman goddess of love and beauty.
As the second-brightest natural object in the night sky
after the Moon, Venus has been a major fixture in human
culture for as long as records have existed, a prime
inspiration for writers and poets as the “morning star” and
“evening star”. Venus surface temperature varies from −151°C
at night to 425°C during the day.
The third planet to the Sun is Earth.
Earth has one natural satellite: the Moon. Surface
temperature varies from −89.2°C to 56.7°C. About 71% of
Earth’s surface is covered with water mostly by its oceans.
The remaining 29% is land consisting of continents and
islands. The majority of Earth’s polar regions are covered
in ice. The combination of Earth’s distance from the Sun,
physical properties, and geological history has allowed life
to evolve and thrive.
The fourth planet from the Sun and the second-smallest
planet in the solar system, after Mercury is Mars ( Red
planet).
It is named after the Roman god of war. Mars has two
relatively small natural moons: Phobos and Deimos. Surface
temperature varies from −143°C to 35°C. Mars has two
permanent polar ice caps. Planet lost its atmosphere billion
years ago. Compared to Earth, the atmosphere of Mars is
quite rarefied.
The largest planet in the solar system is Jupiter, the fifth
planet from the sun
It is named after the Roman god Jupiter. It is a gas
giant planet. Surface temperature varies from –108 °C to?°C.
Jupiter has been called the Solar System’s vacuum cleaner,
because of its immense gravity well and location near the
inner Solar System. It receives the most frequent comet
impacts of the Solar System’s planets. Jupiter has 67
satellites. The four largest moons you can see from Earth
with binoculars on a clear night. They are Io, Europa,
Ganymede, and Callisto.
The second largest planet, after Jupiter in solar system is
Saturn, gas giant and the sixth planet to the sun.
The Romans considered Saturnus the equivalent of the
Greek god Cronus. Surface temperature varies from –139 °C to
? °C. Saturn is best known for the system ofplanetary rings
that makes it visually unique. The particles that make up
the rings range in size from specks of dust up to 10m.
Saturn has 62 known moons, 53 of which have formal names.
The seventh planet from the Sun is Uranus, the third-largest
planetary radius and fourth-largest planetary mass in the
Solar system.
Uranus is named after the ancient Greek deity of the sky
Uranus, the father of Cronus (Saturn ) and grandfather of
Zeus( Jupiter). Surface temperature varies from –197.2 °C to
? °C. Uranus has a ring system. The planet system has a
unique configuration among those of the planets because its
axis of rotation is tilted sideways, nearly into the plane
of its solar orbit. Uranus has 27 known natural
satellites.The names of these satellites are chosen from
characters in the works of Shakespeare and Alexander Pope.
The five main satellites are Miranda,Ariel,Umbriel,Titania,
and Oberon.
The eighth and farthest known planet from the Sun is
Neptune.
It is named after the Roman god of the sea, identified with
the Greek Poseidon. Neptune is not visible to the unaided
eye, the fourth-largest planet by diameter, the third-mostmassive planet, and the densest giant planet in Solar
system. Surface temperature varies from –201 °C to ? °C.
Neptune has a planetary ring system, though one much less
substantial than that of Saturn. The planet has 14 known
moons. Triton is the largest Neptunian moon. The irregular
moon Nereid, has one of the most eccentric orbits of any
satellite in the Solar System.
